Frequently Asked Questions
What is CoQ10?
Coenzyme Q10 (CoQ10) is a vitamin-like substance found naturally in our cells, where it's necessary for energy production - it's often referred to as the 'biochemical spark plug'. It's found most highly concentrated in the heart, one of the most energy-hungry organs in the body, which is why CoQ10 has become such a popular choice for those focused on heart health and healthy ageing.
What is CoQ10 good for?
CoQ10 sits at the centre of your cells' energy production, which is why people take it for vitality and heart health - our CoQ10 120mg is enriched with vitamin B1, which contributes to normal heart function and energy-yielding metabolism. Because the body's own CoQ10 levels naturally decline as we age, it's especially popular with those in their 50s and beyond wanting to support energy and healthy ageing.
Which CoQ10 supplement is right for me?
Three options, three audiences. CoQ10 120mg + B1 is the everyday choice naturally fermented, with added vitamin B1 contributing to normal heart function and energy-yielding metabolism, making it ideal for general heart and energy support. Super Strength 300mg is one of the UK's strongest formulas, for those who want maximum daily support in one capsule. And Ubiquinol 100mg genuine Kaneka Ubiquinol™ is the premium pre-converted form, best suited to the over-50s, whose bodies convert standard CoQ10 less efficiently with age.
What's the difference between CoQ10 and Ubiquinol?
They're two forms of the same nutrient. Standard CoQ10 (ubiquinone) is the well-researched classic, while Ubiquinol is the premium, reduced form - the active antioxidant version your body actually uses, and significantly more bioavailable. Our Ubiquinol 100mg uses only Kaneka Ubiquinol™, the gold-standard branded ingredient, and is particularly popular with those over 50, whose bodies convert standard CoQ10 less efficiently.
Does the body's CoQ10 decline with age?
Yes - our natural CoQ10 levels peak in early adulthood and gradually decline from there, and the body also becomes less efficient at converting standard CoQ10 into its active form as we get older. That's precisely why CoQ10 supplements are so popular with the over-50s, and why we offer Ubiquinol - the pre-converted, highly bioavailable form - for those who want maximum benefit.
What strength CoQ10 should I take?
Our range covers the spectrum: CoQ10 120mg + B1 is the popular everyday choice, naturally fermented and oil-suspended for better absorption; the Super Strength 300mg is one of the UK's strongest formulas for those wanting maximum support; and Ubiquinol 100mg offers the premium bioavailable form, where a lower dose goes further. All three are convenient one-a-day capsules.
When should I take CoQ10?
With a meal containing some fat - CoQ10 is fat-soluble, so it's absorbed far better alongside food than on an empty stomach. That's also why our capsules are oil-suspended, giving absorption a head start. Most people take theirs with breakfast or their main meal; as ever, daily consistency is what counts.
